Seawater contains all the trace elements necessary for life. For reasons that are not yet known, the relative composition of seawater is constant in all the oceans of the world, with the exception of a few variations. It is an extraordinary natural and biological equilibrium.
However, the composition of seawater in absolute values differs depending on the quality of the environment. Each day the tides in the Bay of Mont Saint-Michel, which are the biggest in Europe with a 15-meter rise and fall differential, create powerful tidal streams that renew crystal clear waters, ensure oxygenation and promote the bounty of minerals found in seawater.
This unequalled wealth fosters many therapeutic uses.
